HAY AND GRAIN LOADER.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, DAVID M. Mrnns, a citizen of the United States,residing at l-Iurdsfield, in the county of \Vells and State of NorthDakota, have invented. a new and useful Hay and Grain Loader, of whichthe following is a specification.

This invention has reference to improvements in grain and hay loadersand is designed to provide an attachment for an ordinary hay Wagonwhereby on the progressive movement of the wagon a loading mechanism isbrought into engagement with shocks of grain or hay so that such shocksare first engaged by the loading device and are then lifted by thelatter as the wagon progresses and finally deposited on the wagon, theloading mechanism. then becoming latched and only again moving to theoperative position at the volition of the operator or driver. By thismeans the loading attachment may be normally maintained in the inactiveposition and is only dropped into such relation to the ground as tocatch the shocks when the driver so desires, and, furthermore, provisionis made for the lifting of the mechanism to the inactive position by theprogressive movement of the wagon even though no shocks of grain bepresent to cause the automatic operation of the device.

In accordance with the present invention there is provided a hingedframe at one side of the wagon, usually, though not necessarily, theright side, and this frame is pro vided with fingers in position whenthe frame is active to enter a shock or shocks in the path of thesefingers in piercing relation thereto, and by means of a latch mechanismthe movement of the wagon relative to the shocks upon the ground causesa coupling of an elevating mechanism to one of the wheels of thevehicle, whereby the shock is lifted high enough to pass over the edgeof the rack of the wagon, and from this point it will gravitate into thewagon, while the lifting mechanism is locked in the elevated positionand the actuating wheel is uncoupled from the lifting mechanism, so thatthe wagon may progress without interference. By means of a releasemechanism within the reach of the driver or other operator the liftingmechanism for the shocks may be caused to move again to theactiveposition ready to engage another shock to be set thereby into activemovement to lift the shock and deposit it into the wagon.

The entire stri'icture is of a nature to adapt its application toexisting wagons commonly found in localities where it is desirable togather up shocks for transportation to other places, and theinstallation of the attachment requires no change whatsoever in thewagon structure further than the attachment directly to the wagonstructure of certain members forming parts of the attachment as a whole.

lVhile the device is adapted for the loading of hay and other materials,as well as grain, the description of the structure will be limited forpurposes of simplicity to shocks of grain and the operator will beconsidered as the driver of draft animals.

The invention will be best understood from a consideration of thefollowing de tailed description taken in connection with theaccompanying drawings forming a part of this specification, but whilethe drawings show an operative structure in practical form, it is to beunderstood that there are various changes and modifications of thestructure well within the scope of the invention, and consequently theinvention is not at all limited to the details of structure shown. anddescribed.

Referring to the drawings, there is shown a wagon having front and rearwheels 1 and 2, respectively, carrying a frame having longitudinalmembers 3 and cross members r. provided with the usual rack 5 common tohay wagons or wagons of like character. The showing of the drawings withrespect to the wagon is to be taken as indicative in greater part, sincethe particular structure of the wagon is not material to thepresentinvention and certain parts of the wagon structure are onlyreferred to to facilitate the description.

About midway of the length of the wagon there is secured to thelongitudinal members 3 a frame 6 made up of spaced side members and aconnecting end member 7. The side members are provided with longitudinalslots 8 for the reception of the ends of hook bolts 9 which latter havetheir hook ends in embracing relation to the corresponding longitudinalmembers 3, so that frame 6 is readily attached to a wagon frame withoutany necessity of changing the latter at all, and because of the slots 8the frame may be adjusted in the direction of its length, whichdirection is transverse to the length of the wagon body and because ofthe hook bolts the frame is readily adjustable lengthwise of the wagonbody.

Made fast to the ends of the side members of the frame 6 remote from theconnecting member 7 are brackets 10 of generally trithe other portion ofthe bracket is secured to the same side member at an appropriate purposewhich will presently appear.

distance fromv the end to which the first named portion of the bracketis connected, thus forming a rigid structure. In order to brace thisportion of the structure the bracket 10 toward the front of the wagon isconnected by a brace bar 11 tothe corre sponding longitudinal member 8in position to resist dragging strains. The depending portion of eachbracket 10 is formed with a longitudinal slot 12 by means of which aneye block 13 is bolted to the bracket 10 in any position of adjustmentpermitted by the length of the slot 12. There are two brackets 10 andtwo eye blocks 13 and these latter serve to support a rod 14 free toturn in the blocks and held against longitudinal movement by nuts 15 orotherwise. The rod 14 has fast thereto the corresponding ends of theside members 16 of a substantially rectangular frame, the ends of thisframe connected by the rod 14 being at an angle to the rest of theframe, as indicated at 17, and in order that the ends of the frame whereconnected by the rod 14 may be held in fixed relation one to the other,a bracing strip 18 is carried from one end 17 to the other and securedthereto by belts or rivets or any other manner.

The two side members 16 have secured to their longer ends strips 19' ofappropriate length, these strips being formed with longitudinal slots 20for the passage of sec-uring bolts 21, these bolts extending through theside members 16 and the bolts nearer to the curved ends 17 passingthrough eyes formed in the ends of yoke arms 22, the other ends of whichare connected together and pass through an eye 23 at one end of an arm24, the other end of which is formed with a passage 25 traversed by therod 14 and is secured thereto about intermediate of the length thereofin any suitable manner, so that the arm will participate in any rotativemovement of the rod 14, and the latter fitting snugly in the ends 17 ofthe side members or arms 16 will participate in any movement of thesearms, and consequently with the parts carried by these arms. The arm 24adjacent the eye 23 is formed with a notch or recess 26 for a In orderthat the connected ends of the yoke arms 22 may be secured to the arm24:, these connected ends may be threaded where they pass through theeye 23 and nuts 27 applied to the threaded connected portion of the arms22 on each side of the eye 23 serve to secure the parts together forsimultaneous movement.

In embracing relation to the arm 24 is a yoke 28 carrying a roller 29 inposition to ride along the notched edge of the'arm 24, while the otherend of the yoke 28 is provided with an eve to which is connected one endof a spring 81 preferably of the cylindrical type, while the other endof the spring is connected to a rod 32 carried to and through theconnecting end piece 7 beyond which it may be threaded for theapplication of a nut 33, whereby the tension of the spring is readily adjusted. As will presently appear, the arms 16 and the bars 19 fast tothese arms, to gether with the parts carried by the arms and bars orstrips move about the axis of the rod 14, which latter is substantiallylongitudinal to the wagon and is consequently approximately horizontalwhen the wagon is in operative position, so that the movement of theparts about the longitudinal axis of the rod 14 is in a planesubstantially vertical or perpendicular to the ground or other supportupon which the wagon travels, and for simplicity of description it willbe assumed that the plane of movement of the parts about the rod 14 is avertical plane. The purpose of the spring 31 is to ease the movement ofthe bars or strips 19 and parts carried thereby toward the ground, whilethe same spring will act to facilitate the raising of the bars or strips19 and parts carried thereby, especially toward the termination of theirtravel to the upright position, the range of movement of these barsbeing from an approximately horizontal positlon to an approximatelyvertical position. Assuming that the bars or strips 19 and the partscarried thereby are in a substantially vertical position, as

shown in Fig. 4, the roller 29 of the yoke 28 will rest in a notch 26,but when the parts are moved to the approximately horizontal position,shown in Fig. 3, the arm 24 is raised through an upright position to aposition silghtly inclined away from the wagon body, so that the pull ofthe spring 31 will cause the yoke 28 to ride out of the notch 26 andalong the corresponding edge of the arm 25 until arrested by the rod 14,when it is so near the axis of movement of the bars or strips 19 andparts carried thereby as to have no material effect thereupon, but assoon as the bars 19 are lifted toward the vertical position the arm 24is turned by the upright position until it inclines toward the body ofthe wagon when the yoke 28 will ride toward the notched end of the barand finally lodge therein and to a coinn'iensurate extent assist in theuplifting of the bars or strips 19 and parts carried thereby. Theprimary object, however, of the spring 31 is to ease the fall of thebars .19, which fall is brought about solely by gravity.

The side members or arms 16 are usually made of metal and the strips orbars 19 are usually made of wood, and in order to make web 34, which fora portion of its length may be extended as shown at 35 to partially orwholly embrace the corresponding part of the bar 19. The ends of thearms or bars 16 remote from the ends 17 are bent at an angle to the mainportion of the bar and carried into side engagement one with the other,as shown at. 36, where they may be united by bolts 37.

The ends of the bars 19 remote from the arms or bars 16 are connected bya shoe 33 secured to the bars by bolts 39 or otherwise, and this shoe 38is designed to engage the ground when the bars 19 are in thesubstantially horizontal position to support the outer ends of the bars,the inner ends being supported by the arms or bars 16 and the pivot rod14.

Carried by the outer ends of the bars 19 is a guide finger 40 at aslightly obtuse angle to the bars, so that when the said bars are in thesubstantially horizontal position the outer end of the finger 40 is moreremote from the wagon than the corresponding ends of the bars, thedesign of this finger being to engage shocks and guide them toward thebars 19, the latter, together with the arms 16, constituting the mainportion of the frame of the shock engaging and lifting device. Thefinger 40 may be made of any appropriate material and may be of anyappropriate construction, and if made of metal may be of webconstruction for strength and lightness, but it is usually made of Wood,in which case it may be shaped as indicated in the drawings. Erected onthe bar 19 toward the rear of the vehicle is a frame comprising uprights41 and a connecting cross piece 42, although the particular constructionof the frame is not mandatory. This frame extends from near the outerend of the bar 19 carrying it for an appropriate distance toward thevehicle end of the bar, and adjacent the inner end of the frame there issecured to the two bars 19 a cross bar 43 in divergent relation to thefinger 40. This bar 43 extends a distance forward from the forward bar19 and at the front end has connected to ita rod 44, which latter may beformed with eyes at each end, one eye forming a pivotal connection forthe rod where secured to the front end of the bar 43 and the other endreceives a chain 45 carried to a bracket 46 on the front cross beam 4 ofthe vehicle frame, the purpose of the rod 44 being to resist the drag onthe shock elevating frame, while the chain 45 forms a flexibleconnection permitting the turning of the shock elevating frame about itspivot rod 14. There is, also, secured to the two bars 19 a strip 47 bymeans of hook bolts 48, so that'this strip may be readily adjusted andthe forward end of the strip projects beyond the forward bar 19, whereit is provided with an eye bolt 49 to receive one end of a strand 50,which strand may be in the form of a steel rope, but the particularcharacter of the strand is not material, except that it should beflexible for a purpose which will hereinafter appear.

Extending from the front bar 19 to the connecting men1ber42 of the frameerected on the rear bar 19 is a series of guides 51, each preferablyformed of two associated parallel members, and these guides are slantedto the length of the shock elevating frame, so that the ends connectedto the front bar 19 are nearer the outer ends of these bars than theends connected to. the member 42.

In line with the lower end of each guide 51 is an eye bracket 52 securedto the rear beam 19 by a bolt 53 or otherwise, and each eye bracket 52receives the eye end 54 of a stabbing finger 55, the other end of suchfinger being pointed, as indicated at 56. When the shock engaging andelevating frame is in the lower or active position, the stabbing fingers55, of which there are an appropriate number, are directed forwardly insubstantially perpendicular relation to the bars 19' and insubstantially parallel relation one to the other, each stabbing finger55 projecting through a guide 51 and resting upon the forward bar 19adjacent to the guide 51 individual to the stabbing finger where suchguide is attached to the bar 19. In the particular showing of thedrawings there are four stabbing fingers 55 and four guides, 51, but itwill be understood that this particular number is not mandatory and maybe varied as circumstances may demand. The length of the stabbingfingers 55. is such that they may be forced: into. a shock to asuficient extent to either traverse the same or to positively engage theshock for liftingpurposes when the movement of the fingers into theshock has been arrested by the engagement of the lifting frame with suchshock. The pointed ends of the fingers 55 may stop short of the forwardend of the guide finger 40.

The bar 43 is secured to the top of the bars 19' and there is alsoprovided a strip secured to the bottom of the forward bar 19- and to theforward end of the bar 43, which strip may be made of metal, whilebetween this strip and the bar 13. there is lodged a roller 58 held inposition by a pivot bolt 59.

Pivoted to the finger 40 adjacent the outer end of the forward bar 19 isan arm 60 in traversing relation to. the space between the finger 40 andthe bar and having the end adjacent the bar 43 underriding the latterand resting on the strip Secured to the bar 60 adjacent the bar 3 bymeans of an eye 61 is a flexible strand 62 with the end thereof remotefrom the arm 60 secured to a ring 63 passed through a slot 64; in. one

end of a lever 65 secured by a pivot bolt or pin 66' to the end of oneof the cross beams 4 of the wagon body frame. The lever 65 serves as alatch lever, as will hereinafter appear, and is maintained normally atone limit of its movement by a spring 67 fast at one end to the leverbelow the pivot bolt 66 and at the other end to the adjacent long-i.-tudinal beam 3. of the wagon or vehicle frame. The spring 67 serves tomaintain the lever 65 in a position where the end containing the slot 64is retracted toward the body of the vehicle, this resulting in holdingthe arm 60 in a position where its free end, that is the end lodged. inthe space between the bar 43 and the strip. 57, is held close to. theroller 58, so. that when the device is in operative position and thefingers 55 enter a shock, the arm 60 on the progressive movement of thedevice will ultimately engage the shock and be forced by the sameagainst the action of the spring 67 toward the adjacent bar 19, thisresulting in the moving of' the lever 65 on its pivot 66, so that thelatch end of the lever is moved toward the vehicle body, the spring 67yielding to. such movement and as soon as the pressure on the arm 60 isreleased the spring will return the parts the normal position. Themovement of the arm 60. by the shock is limited by the engagement of thearm. with the forward bar 19.

Mounted on the top. of the bar 43. are hinges 68- carrying a board '69:urged toward the shock receiving end ofthe shock carrier by a spring 7.0connected at one end to one end of the board. and at the other end tothe rear beam 19, the connection to the beam being shown in the drawingsasby way of a chain 71, although this is not mandatory, but preferable.The spring provides for the yielding of the board 69 to-a pressuresuperior to. the resistance of the spring.

The board 69- projects forwardly beyond the front bar 19 to. an extentabout equal to the finger 10 but in divergent relation to the latter, asindicated in Fig. 1, so that the finger 10 and board 69' form adirecting means for the shocks, whereby they will, if somewhat out ofline with the fingers 55, be directed into engaging relation to thelatter.

Secured to a longitudinal beam 3 adjacent an intermediatecross beam ofthe rack supporting frame is a strip 72, and secured to the longitudinalbeams 3 in parallel spaced relation to the strip 72 is another likestrip 73, these strips being made fast to the respective beams 3 by hookbolts 74, so that they may be readily adjusted to: clifferent wagons.The two strips 72 and 73 extend beyond the side of the wagon structureto which the shock elevating frame is secured and support a plate orshelf 75, in the outer edge of which there is formed a notch 76. Theplate 7 5 has secured to its upper surface a latch lever 77 by a pivotbolt 78 or otherwise, and this latch lever has a beveled end 79, back ofwhich the latch is provided with a notch 80 forming a shoulder 81 at thetermination of the beveled end of the latch lever toward the pivot bolt78. The end of the lever remote from the beveled end may have one edgeupturned in the form of a web 82 for purposes of strength and for theattachment of other members, or the lever may be otherwise formed. Thenotch 80 is so positioned as to be substantially coincident with thenotch 76 of the plate or shelf 75, but the lever is movable about itspivot to carry the beveled end away from its notch 76. The plate 75 isso positioned that when the shock elevating frame is moved from thehorizontal to the vertical position the flange extension 35 in embracingrelation to the corresponding portion of the bar 19 is brought intoengagement with the beveled end of the latch lever and the latter isforced to one side about its pivot 7 8, so that the forward bar 19 mayenter the notch 76 and when this bar has entered such notch and movedbeyond the shoulder 81 the latch lever will snap into latching re lationto such bar to thereby hold the shock elevating frame in thesubstantially vertical position. In order to cause the latch lever 77 tohave a normal tendency to snap into engagement with the forward bar 19but yield to the movement of the same into the notch 76, there isprovided a spring 83. one end of which attached to the web 82 and theother end of which may be made secure to any fixed portion of the bodystructure of the wagon, as, for instance, one of the cross bea1ns4.

The latch lever has connected to its beveled end a rod 84, the other endof which is carried to the forward end of the wagon body, where it ispivotally connected to a rock arm 85 on the corresponding end of a rockshaft 86 ournaled in the bracket 46 and provided with another journalbearing 87, both on the forward cross bar 4t of the rack frame of thewagon or vehicle. The rock shaft 86 has at the end remote from the arm85 another arm 88 terminating in a foot plate, 89 which may be locatedwithin easy reach of the foot of the driver of the vehicle, so that suchdriver may operate the rock shaft 86 to cause a movement of the latchlever 77 in a direction to release the bar 19 engaged by this latchlever and thereby permit the shock elevating frame to gravitate towardthe horizontal position, it having a normal tendency to so move becauseof the curved ends 17 of the arms 16, whereby the supporting rod let isnearer the center line of the wagon body than is the latch lever 77.

The shock elevating mechanism in so far as the frame. carrying the shockengaging fingers and coacting parts is concerned has the shoe 38 restingupon the ground when the parts are in position to engage a shock and thewagon with the shock engaging mechanism is caused to travel over theground into operative relation to the shocks, either by draft animals orotherwise. In order to prevent disturbance of the shocks, such as wouldtend to shake out any loose grain therefroi'n, the shock engaging meanscaused to move toward the vertical posi tion as soon as it has safelyengaged the shock, so as to elevate the latter high enough to bedeposited in the body portion of the wagon. For this purpose theprogressive movement of the wagon is utilized and one of the rear wheelsis employed as an actuating wheel to cause the desired movement of theshock engaging means toward the vertical position for the lifting of theengaged shock and the deposition thereof in the wagon. The actuatingmeans provided by the present invention may be attached to the wagonwheel and wagon body without any change in the latter, the entire changein the normal wagon structure necessitated by the installation of thepresent invention being limited to the boring of a few bolt holes andthe insertion of a few screws, but no change whatsoever requiring anymodifying of the structure of wagons of existing types is demanded.

The rear wheel 2 on the side of the wagon to which the shock elevatingframe is attached is provided with a winding mechanism, and this windingmechanism has associated therewith certain parts carried by the wagonframe structure to cause the operation of the winding mechanism undercertain circumstances and to render the latter inactive under othercircumstances.

The parts directly connected to the rear wheel, and the parts directlyassociated therewith are best shown in Figs. 5 to 10, both inclusive.There is attached to the wheel 2 a ring 90, by means of a suitablenumber of brackets 91, each attached to about a middle point on theinner face of the ring and then bent away from the ring toward thecenter thereof and then into parallel relation with the ring with theend remote from the ring at an angle to the bent away portion and shapedto fit a wheel spoke to which it may be attached by a bolt or screw 92.An appropriate number of these brackets may be provided. While it ispreferable that this ring should be concentric with the axis of rotationof the wheel, mod erate eccentricity is not at all material to theproper working of the structure. Mounted on the ring 90 is an incompleteband 93 preferably having a slight elasticity so as to tend to a smalldegree toward the straight position. Secured at intervals to oppositesides of the band98 are strips 94 each terminating at one end in anoutstanding finger 95 and at the other end in an ear 96 adapted to extend toward the center of the ring 90 and at the end provided with aroller 97 in position to engage the inner face of the ring 90. The endsof the strips 91 carrying the fingers 95 may be provided with holes 98for the passage of rivets or other fastening means, whereby these stripsare attached to the band 93 or the roller ends of these strips may beheld together by a clip 99 having its ends in embracing relation to thestrips and its connecting part extending between these strips.

By these means the strips may be readily attached to the band with therollers in embracing relation to the ring 90, or other means may beprovided whereby the band is held to the ring and means similar to theoutstanding fingers 95 are provided to form the band into a pulley likestructure, there being a sufficient number of the pairs of outstandingfingers 95 or other devices adapted to a like purpose for guiding astrand around the band, as will hereinafter appear.

The fastening means for securing the strips 91 to the band 90, whichfastening means traverse the openings 98, may be so related to thestrips that the latter can be turned on the fastening means as pivots,and then when for any reason it is desirable to remove the band from thering 90 it is only necessary to unbend the ends of the clips 99 fromembracing relation to the strips 91 and the said strips may be turned ontheir pivots to carry the rollers 97 from engagement with the inner faceof the ring 90, so that the entire band is released and may be removedfrom the ring. The reverse operation will result in the securing of theband to the ring.

One end of the band 93 is made fast to a clutch device comprising twoU-shaped members 100 and 101 having the free ends, of the like legsconnected together by links 102, so that these members 100 and 101 may jswing toward and from each other at the yoke ends.

the strip 103 carried by the other leg.

the links 102.

The member 100 has fast to its yoke portion an angle finger 106 inposition to project laterally beyond the corresponding edge 1 of thering 90, and the other member 101 has a curved finger 107 projectinggenerally to- Ward the center of the ring 90 and also in a The band 93has its end made; fast to the member 100 and both members have strips103 made fast to the leg portions, these strips terminating in angleextensions 5 104 adapted to extend in embracing relation to the angleface of the ring 90, one exteni sion 101 of one leg of each member 100and 1'01 projecting toward the extension 101 of The two members 100 and101 are constrained; one toward the other by springs 105 0011-? nectedto the like legs of these members he i tween the yoke ends of themembers andformed with a notch 126 matching the notch 125 and providedfor a like purpose. The

direction outward from the plane of the outer edge of the ring 90, theouter edge of the ring being that remote from the wheel to which thering is secured. Furthermore, there is made fast to the member 100 aconnecting ring 108 to which is secured the end of the strand 50 comingfrom the bar 17 before mentioned and traversing a path to be presentlydescribed.

The cross beams 41 of the wagon frame locatecl adjacent the rear wheel 2under consideration have made fast thereto extension strips 109, andthese extension strips have made fast thereto by hook bolts 110 anotherstrip 111 extending from one strip 109 to the other in a positionoutside the wheel 2' and the ring 90 carried thereby, that is, the strip111 is farther from the wagon body than is the wheel 2. The strip 111carries a bracket 112 to which is pivoted a lever 113 by a pivot rod orbolt 114:, the bracket being so shaped as to bring the pivot of thelever 113 close to the axis of rotation of the ring 90 in the particularshowing of the drawings, although this exact arrangement is notmandatory. The lever 113 is of the first order and has one arm at nearlyright angles to the other, so that the lever is in the nature of a bellcrank lever. One angle arm of the lever is provided with a longitudinalslot 115 and the other arm of the lever terminates in a substantiallyright angle extension 116. Connected to the slotted end of the lever isan eye member 117, a bolt 118 being employed for connecting the eye 117to the slotted end of the lever, so that this eye member may be securedat any point of adjustment length wise of the slotted arm of the leverwithin the limits of the slot 115. The eye member 117 has connectedthereto one end of a rod or link 119, the other end of which isconnected to a slidable bar 120 mounted on a guide strip 121 made fastto the supporting bars 72 and 73 beneath the plate 75, the bars be ingappropriately notched for the passage of the bar 120 and the supportingstrip 121. This strip 121 extends beyond the bar 72 toward the front ofthe machine, where it may be upturned, as indicated at 122, and providedwith a passage for the sli-dable bar 120 to guide the same and a likeupturned end 123 may be provided at the rear end of the bar 73 for alike purpose. Further1nore,-the forward projecting end of the strip 121may have a stiffening flange124, formed on one side. The guide strip 121is formed with a notch 125 for the entrance of the latch end of thelever 65 and the slidable plate 120 is end of the slidabl'e bar 120remote from that connected to the rod or link 119 has connected theretoone end of a spring 127, the other end of which is made fast to a fixedportion of the frame of the wagon body, say

the front cross piece or beam 1, the spring having a normal tendency tocarry the bar 120 toward the front of the vehicle.

Pivoted to the plate or table 75 and underlying the same is an anglelever 128 shown separately in Fig. 13. One arm of this lever 128 has itsend bifurcated, as indicated at 129, and embraces the end of theslidable bar 120 close to the connection therewith of the rod or link119, so that movement of the bar 120 under the action of its spring 127will cause a rocking of the lever 128 about its pivot support indicatedat 130 because of the engagement with this lever of the link 119 whereconnected to the bar 120. The other end of the lever 128 is "ofsuflicient length and so shaped as to be movable in traversing relationto the notch or recess 76 in the plate or table 75 and the range ofmovement of the lever 128 is such that when the bar 120 is released tothe action of its spring 127 the end of the lever 128 adjacent the notch76 is carried to the open end of this notch, so that when the shockelevator is lifted and the corresponding bar 19 thereof enters the notch76 the lever 128 is engaged thereby and turned on its pivot support 130in a direction to cause the bifurcated end 129 to engage the link 119and force the bar 120 lengthwise against the action of the spring 127,extending the latter, and this movement is continued until the latchlever 65, under the action of the spring 67, snaps into the notch 12Gnltimately brought into its path, thus locking the bar 120 againstreturn movement under the action of the spring 127, so long as the lever65 is under the control of the spring 67. There is also made fast to thestrip 111 in pendent relation thereto a bracket 131 in the path of thefinger 10G carried by the member 100 to which the band 93 is secured,the purpose of this bracket 131 being to arrest rotative movement of theband in. one direction. There is also carried. by the strip 111 apendent angle bracket 132 in the path of the finger 107 when the band 93is rotating with the wheel 2 in the forward movement of the vehicle.Carried by the strip 111 is another angle lever 133 con nected to thestrip 111. so as to move in sub stantial parallelism therewith by apivot support 134, which may be in the form of a bolt. The lever 133 hasone arm provided with a longitudinal slot 135 for a bolt 136 or othersuitable fastening device connecting an eye member 137 to the slottedend of the lever in any desired position of adjustment, this eye memberhaving pivotally connected thereto one end of a rod or link 138, theother end of which is extended to and pivotally connected to the flange82 of the latch lever 77, so that the lever 133 participates inmovements of'the latch lever 77, The other arm ofthe lever-1.551s pprted by an elongated keeper bracket 139 fast to the under face of thestrip 111, and beyond this keeper bracket the lever is bent at an angleto form a pendently disposed member 1 10 terminating in a return portion1 11 car rying a laterally extended head 14.2, so po-' sitioned as to benormally in the path of the finger 106.

Returning to the strand 50, it will be observed that after leaving thebar 47 it is carried about a pulley 113 fast to an appropriate part ofthe frame of the wagon body, and by this pulley the direction of travelof the strand is changed and it is carried about another pulley 141 1below the pulley 1413 and from this pulley l-tst the strand is carriedtoward the rear of the vehicle about still another pulley 141:5 mountedon an appropriate portion of the wagon frame or body, and from the lastnamed pulley the strand passes to the ring 108.

Mounted in suitable bearings 141-6 on the side of the body of rackcarried by the framework of the Wagon is a rock shaft 147 having at oneend, which is the front end, coextensive with the front end. of thewagon body, a rock arm 148 connected by a link 149 to a hand lever 150in position to be manipulated by the driver. rear end of the rock shaft147, is bent into a return member 151 to constitute a rock arm inoperative relation to the latch end of the lever 65 to actuate saidlever in opposition to its spring 67 and in the same direction in whichit is moved by the strand 62.

When a wagon equipped as has been described is driven to the field wherethe shocks are located, the shock elevator is in the substantiallyupright position shown in The other or i Fig. 4, being locked. in suchposition by the latch lever 77 At the same time the strand 50 is in partwound upon the band 93, and is thereby maintained in but a slightlyslack condition, the finger 106 being then in en gagement with the head142 and the latch structure made up of the members 100 and. 101 being inungripping relation to the ring 90, so that the latter may turn freelywith the wheel 2, the rollers 97 presenting an antifriction support forthe band The wagon is driven into such relation to the shocks as thedriver may desire, and then by a proper pressure upon a foot member 89of the arm 88 the shaft 86 is rocked in a direction to act. through thelink 84: to move the latch end of the lever 77 in a direction to carrythe shoulder 81 out of engagement with the bar 19, previously locked bythe latch end 79 of the lever and the shock elevating frame thengravitates toward the ground moving about the bearings of the rod 11 asa pivot support. The fall of the shock elevator is eased by the spring31 as already described, and ultimately theshoe 38' contacts with theground, thus support ing the shock elevator in a position slightly Ithese latter serving to support the shock and elevated above the ground.The fall of the shock elevator draws on the strand in a direction tomove the band 93 counter-clockwise as viewed in Fig. 2, and this ispermitted since the movement of the lever 77 to the unlatched. positioncaused through the link 138 a rocking movement of the lever 133 in adirection to move the head 142 out of the path of the finger 106, sothat there is presented no obstruction to the unwinding of the strandfrom the band 93, which operates after the manner of a winding drum. Theparts are so proportioned that when the shock elevator is in the loweredposition the finger 100 is sufliciently close to the stop bracket 131 toprevent undue unwinding of the strand although permitting theaccommodation of the shoe 38 to varying levels of the ground, withoutslacking the strand 50 or putting it under strain to any materialextent.

The driver directs the horses or other propelling means so that thestabbing fingers are brought into engagement with a shock or the shockis moved into engagement with these fingers by the guiding finger 40.The progressive movement of the wagon causes the pointed ends 56 of thefingers 55 to enter the shock without any material disturbance of thelatter and ultimately the arm 60 is brought into engagement with theshock and the weight of the latter is suflicient to move the arm 60 toactuate the strand 62 in a direction to rock the lever 65 against theaction of the spring 67, the movement being sufficient to withdraw thelatch end of the lever from the notch 126 of the slidable bar 120, andthis slidable bar is then free to move under the action of the spring127 in a direction to carry the lever 128, so that its appropriate endis in traversing relation to the entering end of the recess and the link119 draws the lever 113 in a direction to cause the inner extension 116thereof to engage the finger 107 of the gripping mechanism to which theband 93 is connected, so

that the member 101 of the gripper is moved away from the member 100,the latter being held by the strand 50 against movement, and the angleextensions 10% are broughtinto gripping engagement with the inner faceof the ring 90, whereupon the rotative movement of the ring 90 with thewheel 2 causes an actuation of the band 93 with the ring 90 and thestrand 50 immediately begins to wind upon the band 93 as upon a drum,the fingers 95 acting as guides and the strain on the strand 50 servingto maintain the gripper in firm engagement with the ring 90, the finger107 in the meantime moving away from the extension 116.

The progressive movement of the wagon causes an elevating movement ofthe shock elevator with. the shock fast heret eca se of being pierced bythe stabbing fingers 55,

carry it along with the shock elevator without disturbance, and thislifting movement continues until the latch end 79 of the lever 77 isengaged by the corresponding bar 19, the extension 35 of the flange 34serving as a wear plate, and the lever 77 is forced out of the path ofthe bar 19 against the action of the spring 83 until the bar has passedthe shoulder 81, when the spring 83 becomes active to rock the lever 77to bring the shoulder 81 into obstructing relation to the bar 19. At thesame time the movement of the lever 77 has caused a movement of the head1452 out of the pat-h of the oncoming finger 100 of the gripper carriedby the band 93,

the parts being properly timed for the purpose, and the gripper hasmoved by the time the bar 19 is seated behind the latch head 79 intoengagement by its finger 107 with the bracket 132, so that the gripperis forced to the ungripping position andthe band 93 is released from thering 90, whereby the wheel 2 may continue to rotate without affectingthe band 93 which now remains quiescent, except that it may movebackwardly until arrested by the head 142, thus relieving the strand 50from strain, the slight slack of the strzlind under these conditionsbeing immater1a As the shock elevator or carrier approaches the uprightposition the weight of the shock is borne by the board 69 held by thespring 70 and about the time that the shock carrier or elevator ismoving into engagement with the latch lever 77 the weight of the shockis sufficient to overcome the spring 70 and the board yields thereto,while the inclined position of the guides 51 which now have the endsconnected to the forward bar 19 more elevated than those connected tothe strip 412 permits the movement of the fingers 55 along these guides51 until they assume a declined position, such as illustrated in Fig. 4,and ultimately the fingers reach the ends of the guides adjacent thestrip a2, then the yielding of the board 69 permits the shock togravitate from the fingers 55, the shock sliding along these fingers andbeing directed by them and by the board 69 into the rack or body portionof the wagon or vehicle. It will be observed that the discharge of theshock from the stabbing fingers is due solely to the action of gravity,while at no time is the shock before entering the body of the vehicle ina position where there is a liability of loss of any loose grain, whichloss often occurs where shocks are loaded into wagons by hand. It willbe observed that the shock elevator when released moves to activeposition solely by the action of gravity, and by such movement sets thereturn mechanism in position to cause the eleva ion of.

the shock lifter and loader by the progressive movement of the vehiclein coaction with the shock itself, while the discharge of the shock fromthe elevating devices is accomplished solely by the action of gravity,the weight of the shock causing the fingers or tines 55 to move underthe direction of the guides 51 toward the pendent position, so that theshock readily slides therefrom.

As the shock carrier is elevated and comes in contact with the lever 77the movement of the latter to permit the passage of the forward bar 19into the recess 7 6 has caused the operation of the lever 133 in themanner before described, and at the same time the lever 188 is actuatedto return the bar 120 to a position where the latch lever 65 may enterthe notch 126, to which last position it is constrained by the spring67. As the shock elevator is moved about the axis of the rod 14 to theelevated position, the ring 63 slides along the slot 64, since the arcdescribed by the eye 61 to which the rope or cable 62 is attached is onan axis displaced with relation to the slot 6 1 and consequently theslot provides for the changing relation without putting the strand orrope under undue strain. XVhen the next shock in order is approached,the operator manipulates the foot member 89 to cause a release of theshock elevator, so it may gravitate again to the ground in position toengage and elevate the shock being approached, and this operation may bere peated from time to time as may be found necessary.

It sometimes transpires that after the shock elevating mechanism hasbeen lowered to the ground, it is desirable that it be elevated withoutengaging a shock, and for this purpose the lever 150 is manipulated bythe driver to rock the shaft 147, causing thereby a movement of the arm151 into engagement with the latch end of the lever 65, thus withdrawingthis lever from the notch 126, permitting the spring 127 to move the bar120 in a direction to cause the lever 113 to actuate the gripper in amanner to couple the band 93 to the ring 90 and thus cause the windingof the strand or rope 50 on said band, and by this operation cause theelevation of the shock engaging and elevating means irrespective of thefact that the arm 60 has not been engaged by a shock.

It will be observed that provision is made for adjustments throughoutthe structure where such adjustments may be needed to adapt theattachment to wagons of different kinds, and it is because of these manyadjustments that such adaptation is possible, and, furthermore,adjustments are provided for the establishing of the time relation ofportions of the structure whereby not only is there compensation forwear but the time relation of the several parts may be changed asoccasion may demand. It will also be observed that the united ends ofthe members 22 are threaded for a sufficient length to provide foradjustments whereby the spring carrying yoke 28 may be made to ridealong the arm 25 at any period, within limits, of the approach of theshock elevating device to the ground, so that the casing of this shockelevating device may continue as long as found advisa le.

Since the attachment adds weight to one .side of the wagon, it isusually advisable to add to the fifth wheel or circular plate or ring152 rollers 158 secured to the front bolster, so that there may not beexcessive wear upon the bearing surfaces. 1
